Supplements vs. Prescription Modafinil: Which Makes You Smarter?

by Chris Centeno, MD /

Let’s face it, we MDs can be pretty smug sometimes. We often believe that with our universities and research, we know it all. Hence, I love studies that show that sometimes all of what we think we know isn’t enough. The most fun “naked in Times Square” moments for modern pharmaceutical-based medicine are when a cheap and widely available supplement beats or holds its own versus an expensive drug. This morning’s blog is on how common memory supplements did just that. Let me explain.

Modafinil: the ‘Smart’ Drug

Modafinil is a stimulant or “upper,” which means it promotes alertness and wakefulness, so it is often used to treat sleep disorders in those who have severe problems staying awake. In the U.S., modafinil is a pharmaceutical drug that requires a prescription. This drug has also managed to carve out a reputation as a ‘smart’ drug, or an aid to greatly enhance mental focus and concentration.

Modafinil is in the same US-regulated controlled substance category (schedule IV) as benzodiazepines, such as Xanax, Librium, Valium; barbiturates, such as phenobarbital; and so on. Hence, it should be prescribed with caution due to its side effects. These can include all of the common issues with other stimulants, like not being able to get to sleep, hallucinations, changes in mood, and so on.

Bacopa and Ginseng: the ‘Smart’ Supplements

Commonly known as waterhyssop and found growing in wetland environments, Bacopa monnieri, is a common herb used in Ayurvedic medicine, a holistic and ancient medicine that originated in India and focuses on a mind, body, and spirit balance to promote healing and maintain health.

Bacopa could be called the ‘smart’ herb as for thousands of years, it, too, has been used to improve memory and other cognitive conditions. And many swear it makes them smarter by enhancing their mental focus and concentration. Its benefits don’t stop there. Bacopa monnieri is not only known as one of the ‘smart’ supplements, it’s also known for reducing stress, anxiety, and depression; possibly treating Alzheimer’s and reducing seizures in epilepsy; relieving chronic pain; and much more.

Ginseng is a root herb that has also been associated with improved mental focus and concentration. Ginseng has been a staple of natural herbal medicine for centuries, and, again, many swear by its benefits. There are many types of ginseng; a couple of the more common are Asian (Korean) ginseng and American ginseng. Ginseng is also known for reducing stress, lifting mood, reducing inflammation, suppressing appetite, increasing sex drive, and much more.

While Bacopa seems to have a more chronic long-term effect on concentration improvement, ginseng’s effect seems to be more acute, or short term. In other words, taking Bacopa regularly (like a daily vitamin) may keep mental focus sharp long-term, but if you just need a quick mental pick-me-up, ginseng may do the trick. A new study set out to determine if Bacopa monneiri and ginseng could hold their own against the prescription drug modafinil in their ability to enhance mental focus and concentration. The results were interesting. Let’s take a look.

‘Smart’ Drug vs. ‘Smart’ Supplements for Mental Focus 

The new study pitted both ginseng and Bacopa against the prescription drug modafinil. The new study aggregated results from prior double-blind randomized controlled trials (a meta-analysis). This means that in these studies both participants and investigators didn’t know which group was the test group and which was the control group (given a placebo). All of the studies provided data on modafinil, Bacopa, or ginseng and their cognitive outcomes. What did the researchers discover?

The cognitive effects varied depending on the treatment. For fast mental processing, modafinil was the winner. For enhancing memory and focus on learning, Bacopa, taken regularly, took first place here. For boosting secondary memory (or stored memories) and performing quick-reaction-based tasks, ginseng was the clear victor.

So which makes you smarter depends on the kind of “smarts” you’re looking for, but according to the researchers, the natural herbs (i.e., nutraceuticals) ginseng and Bacopa had comparable cognitive effects to the controlled-substance pharmaceutical modafinil.

Other Ways to Get a Memory Boost

While Bacopa and ginseng may be a good natural alternative to the pharmaceutical modafinil, I’ve also covered a few other studies that provide possible tips to boosting memory. The first one is easy. All you have to do is sleep. The harder part here for some, however, is that it must be a good night’s sleep. Sleep may strengthen important memories by purging out the weaker memories we don’t need.

Green tea has been all the rage for its many potential health benefits, and one of those appears to be its ability to enhance memory. Taking a turmeric/curcumin supplement may also aid memory by regenerating nerve stem cells and keeping the brain healthy. Finally, the negative anesthesia effects following surgery include a memory decline, cognitive changes and a postoperative dementia risk that increases with each surgery. In this case, it’s not about boosting memory but retaining the memory you have by avoiding big surgeries.

The upshot? It’s always amazing to me that an herb or root that’s been thought to help memory for thousands of years really works in a modern randomized controlled trial. Even more amazing is that you can get these supplements for pennies on the dollar compared to Modafinil and without the crazy side effects of that drug. Turns out the ancients actually did know a thing or two!

    A known cause of “delayed word recall” is chronic TBI. It appears that BM supplement could help such patients to some extent. Great blog – thanks!

  2. Bobbie Velasquez

    Do you sell these drugs or are able to say where to get them?

    1. Regenexx Team

      Bobbie,
      No, sorry we don’t. A good quality health food store should carry them.

  3. DAVE ETGES

    Beware, Bacopa can have side effects, too. It left me with a next day groggy feeling that would not go away. Forget about trying to work out. Those effects took about ten days to go away after I stopped taking it. Use caution!

      DAVE,

      Thank you for the feedback. It’s a very interesting study, which will hopefully lead to further research, but caution always needed.

Shoulder

Shoulder

Many Shoulder and Rotator Cuff injuries are good candidates for regenerative treatments. Before considering shoulder arthroscopy or shoulder replacement, consider an evaluation of your condition with a regenerative treatment specialist.

  • Rotator Cuff Tears and Tendinitis
  • Shoulder Instability
  • SLAP Tear / Labral Tears
  • Shoulder Arthritis
  • Other Degenerative Conditions & Overuse Injuries

Cervical Spine

Spine

Many spine injuries and degenerative conditions are good candidates for regenerative treatments and there are a number of studies showing promising results in treating a wide range of spine problems. Spine surgery should be a last resort for anyone, due to the cascade of negative effects it can have on the areas surrounding the surgery. And epidural steroid injections are problematic due to their long-term negative impact on bone density.

Knees

Knees are the target of many common sports injuries. Sadly, they are also the target of a number of surgeries that research has frequently shown to be ineffective or minimally effective. Knee arthritis can also be a common cause for aging athletes to abandon the sports and activities they love. Regenerative procedures can be used to treat a wide range of knee injuries and conditions. They can even be used to reduce pain and delay knee replacement for more severe arthritis.

Hip

Hip injuries and degenerative conditions become more common with age. Do to the nature of the joint, it’s not quite as easy to injure as a knee, but it can take a beating and pain often develops over time. Whether a hip condition is acute or degenerative, regenerative procedures can help reduce pain and may help heal injured tissue, without the complications of invasive surgical hip procedures.

  • Hip Arthritis
  • Hip Bursitis
  • Hip Sprain, Tendonitis or Inflammation
